PANEL-BOARD CONSTRUCTION.

Application led August 2, 1915.

To all unto/n. 'it may concern:

Be it known that I, EDWIN A. OLLEY, a citizen of the YUnited States, residing at Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Panel-Board Construction, of which the following is a specification.

This invention relates to panel boards, and has for its object a particularly simple panel board construction by which the Width of the board is reduced to a minimum; and it consists in the con'ibinations and constructions hereinafter set forth and claimed. Other objects will appear throughout Ithe specification,

In describing this invention, referenceis had to the accompanying drawings, in which like characters designate corresponding parts .in all the views.

Figure l is a plan View ofthe panel board, the electrical appliance forming part of this invention, heilig removed.

Fig. 2 is a sectional View, partly in elevation, oir' the electrical appliance omitted in Fig. 1, the base and the bus bars of the panel board being also shown partly insection.

F ig. 3 is a fragmentary detail view, showing in plan. a portion of Vthejbody ot' the electrlcal appliance in full, and also showing 1n plan a portion ot' the mechanism Within the body of the electrical appliance, parts or' said mechanism being removed, the underlying bus bars being also shown.

Fig, Il is an inverted plan view of the electrical appliance, parts being removed.

The panel board construction comprises, generally, a base, bus bars mounted on lthe base, an electrical appliance including van insulating body detachably mounted above the bus bars, load circuit controlling devices carried by the body and removable ytherewith, and also load circuit terminals or bars carried by the body and removable therewith.

I have here illustrated my invention as embodied in a panel board for a three wire system.

1 is the base of the panel board, and 2, 3 and 4i are respectively the outside bus bars and the neutral bus bar mounted on the tace of the base in parallelism With each other.

5 is the insulating body of the electrical appliance. The body is mounted on the base, extends crosswise ot the bus bars )2, 3 and i and rests at its lower edge on the base, it

two double switches, and two pairs of fuse receptacles carried by each -body 5. The body 5 is here shown in the form of a housing open at its lower side and having fuse sockets 6 on its top, the switches being housed within the body 5.

7 and 8 are 'the members of the pairs of load circuit bars carried by the body 5 at opposite ends thereof, the bars 7 and 8 of each pair being connected to one oi' the outside bus bars 2 0r 3, and to the neutral bus bar 4 through switches and tuse devices which are connected in series therewith, as will be understood vby those skilled in the art.

The mechanism of each. switch is supported by a bridge 9 extending crosswise oi the body near the lower side of the body, and includes a pair of rocking switch arms l0 and 11 and means for operating' the switch arms, as the operatingA push buttons 100. As the operating means is well known itv is thought further description is unnecessary, it beingonly of importance in so far as lthis invention is concerned. that the push buttons 10a extend upwardly through the top' of the body 5 orto the outside of the body, so as to be operated from the front side of the panel board. A

The switch arm 100i? each switch mechanism engages at its opposite ends with contacts 12, 13 and the switch arm ll with contacts 14, 15. The contacts l2 and 14 are carried by terminals 16 and l? which are mehanically secured and electrically connected byscrews 18 to upwardly extending portions 19 off the load circuit bars 'land 8. The screws i8 extend through the end wall of the body 5, through the portions 19 lap- 'ping the inner tace of the said end wall, and into 'the base flanges of the conductors 1S, i7. The contacts 13 and i5 are carried by conductors 20, 2l having arc-shaped portions iapping or lying the inner face ci Lili) the body 5 and-secured in position as hereinafter described. y

The fuse plug receptacle of each pair includes the usual sleeve terminal 22 or and the central terminal Q3 or Q4, the sleeve terminals 29, 22 each having the usual inturned base flange resting on the bottom of the socket G and. overlaid by a Washer The sleeve terminals are electrically connected to the arc-shaped conductors Q0, 21'

by screws 2G extending through said arcshaped conductors, holes in the top of the body 5, the inturned lianges of the sleeves, and into the Washers 25.

The central terminal 23 of one of these fuse plug receptacles is a screw extending through the top of the body 5, and a depending boss 5b on the top, and threading into the upper end of a post 28 rising from one of the bus bars 2 or 3. The central termi nal 24 of the other fuse plug is a screw ex tending through the top of the body 5 and a depending boss 5b and threading` into one. end of a conductor or bar Q9 lying contiguous to the inner face of the top ot' the body 5, the barsl) extending across the upper end of a post 30 rising from the neutral bus bar 4 and being connected to said post by a screw 31 located in a hole in the top ot' the body 5 and extending through a. hole in the bar 29 and threading into the upper end of the post 30. This bar Q9 is common to tivo fuse plug receptacles, as the. electrical appliance here shown is of double construction and adapted for a three wire system.

The load circuit bars 7 and S lap or lie on the upper face of the base. 1, and are secured thereto by suitable binding devices for the load circuit Wires. Said binding dcvices as here illustrated consist of screws 32 extending through the base 1 `trom the rear or lower side thereof and through the bars 7, 8, and binding nuts 33 screwing on thc upper ends of the screws. (.)bviously the electrical appliance is held in position by the screws 23, 24;, 31, 32.

ln operation when fuse plugs are inserted in the plug receptacles and one of the switches operated, so that the arms 10 and 11 connect the contacts 12, 13 and 14, 15, the current passes Jfrom one outside bus bar 2 or 3 through the post Q8, central terminal 23. fuse plug to the sleeve terminal 22, then to conductor 21 and.the contact 15 thereof, switch arm 11, contact 14, load circuit bar through the load circuit, load circuit bar 7. switch contact 1Q, switch arm 10, contact 13, conductor 20. through the sleeve terminal 22 of the other fuse plug receptacle, through the fuse plug and the central terminal :24, bar 29 and post 30 to the neutral bus bar st.

This panel board construction is particularly advantageous .in that all circuit con-- trolling devices and the load circuit bars are removable as a unit, yand this unit is so arranged `that the width of the panel board is reduced to a minimum compared with other ty 'ies of panel boards.
